5-Methoxy-2-methyl-1-(thiophen-2-yl)pentane-1,3-dione CAS 1250722-17-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methoxy-2-methyl-1-(thiophen-2-yl)pentane-1,3-dione.

CATO supplies 5-Methoxy-2-methyl-1-(thiophen-2-yl)pentane-1,3-dione (CAS 1250722-17-8), a certified reference material (molecular formula C11H14O3S, MW 226.29 g/mol) for analytical method development and quality control.

Structurally, 5-Methoxy-2-methyl-1-(thiophen-2-yl)pentane-1,3-dione (C11H14O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 226.29 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
